Corrective | The error message is displayed when the Linux Small Computer System Interface (SCSI) mid- |
Action: | layer asks for physical disk cache settings. The controller firmware manages the virtual disk |
| cache settings on a per controller and a per virtual disk basis, so the firmware does not |
| respond to this command. The Linux SCSI |
| policy is |
| virtual disk. |
| See the topic |
| Except for this message, there is no effect of this behavior on normal operation. The cache |
| policy of the virtual disk and the I/O throughput are not affected by this message. The cache |
| policy settings for the PERC SAS RAID system remain unchanged. |

The driver running in the new kernel is the native driver of the new kernel. The driver package you installed previously in the new kernel does not take effect in the new kernel:
1.Type: dkms build

Unable To Register SCSI Device Error Message
Error: | smartd[smartd[2338] Device: /dev/sda, Bad IEC (SMART) mode |

| device /dev/sda at line 1 of file /etc/smartd.conf. |
Corrective | This is a known issue. An unsupported command is entered through the user application. User |
Action: | applications attempt to direct Command Descriptor Blocks to RAID volumes. The error |
| message does not affect the feature functionality. The Mode Sense/Select command is |
| supported by firmware on the controller. However, the Linux kernel daemon issues the |
| command to the virtual disk instead of to the driver IOCTL node. This action is not supported. |
